Displays news items from selectable CNN News RSS feeds, inline, as a widget or in a theme. Multiple feeds allowed. Caching.

Olav Kolbu

CNN has a number of RSS feeds with current news available, on a 
number of topics. This widget allows the WP admin to select which 
feed, how many items to show from that feed and optionally set a 
widget title. If no title is selected, the name of the feed is 
used. The feed is fetched for every view, so users are guaranteed 
up to date information. No local storage of feed is done. 
Clicking on a news item will of course take you straight to the 
relevant article at CNN, as per CNN Terms of Use.
This plugin works both as a widget, as inline content 
replacement and can be called from themes. Any number of 
inline replacements or theme calls allowed, but only one 
widget instance is supported in this release.
For widget use, simply use the widget as any other after 
selecting which feed it should display. For inline content 
replacement, insert the one or more of the following strings in 
your content and they will be replaced by the relevant news feed. 
For theme use, add the do_action function call described below.
<ol>
<li><code></code> for the default feed</li>
<li><code></code></li>
</ol>
Shortcodes can be used if you have WordPress 2.5 or above, 
in which case these replacement methods are also available.
<ol>
<li><code>[cnn-news]</code> for the default feed</li>
<li><code>[cnn-news name="feedname"]</code></li>
</ol>
Calling the plugin from a theme is done with the WP do_action() 
system. This will degrade gracefully and not produce errors 
or output if plugin is disabled or removed.
<ol>
<li><code><?php do_action('cnn_news'); ?></code> for the default feed</li>
<li><code><?php do_action('cnn_news', 'feedname'); ?></code></li>
</ol>
Enable plugin, go to the CNN News page under 
Dashboard->Settings and read the initial information. Then 
go to the CNN News page under Dashboard->Manage and 
configure one or more feeds. Then use a widget or insert 
relevant strings in your content or theme.
Additional information:
The available options are as follows.
Name: Optional feed name, that can be used in the 
widget or the inline replacement string to reference 
a specific feed. Any feed without a name is considered 
“default” and will be used if the replacement strings do 
not reference a specific feed. If there are more than 
one feed with the same name, a random of these is picked 
every time it is used. This also applies to the default 
feed(s).
Title: Optional, which when set will be used in the 
widget title or as a header above the news items when 
inline. If the title is empty, then a default title 
of “CNN News : <region> : <feed type>” is used. Note 
that as per CNN Terms of Service it is a requirement 
to state that the news come from CNN.
Feed: A dropdown list of the current feeds provided 
by CNN. This list is hard coded into the plugin, presumably 
CNN does not change the list too often. The [INTL], [MONEY] 
and [SI] after the feed name indicate that the feed is from 
CNN International, CNN Money or Sports Illustrated respectively.
News item length: Short or long. The short version is really just 
the news item title as a one liner but probably the one most 
WP admins will use. The long version is the title followed by 
a 3-4 line teaser. For the short version, the long text is 
available as a mouse rollover/tooltip.
Max items to show: As the title says, if the feed has 
sufficient entries to fulfil the request.
Cache time: The feeds are now fetched using WordPress 
builtin MagpieRSS system, which allows for caching of feeds 
a specific number of seconds. Cached feeds are stored in 
the backend database.
Clicking on a news item will of course take you to the 
relevant article at CNN, as per CNN Terms of Use.
If you want to change the look&feel, the inline table is 
wrapped in a div with the id “cnn-news-inline” and the 
widget is wrapped in an li with id “cnn-news”. Let me 
know if you need more to properly skin it.
Note that if you get the message “CNN News unavailable” then 
the WordPress internal RSS feed fetcher failed to get the 
feed. Reasons for this are firewalls blocking outbound traffic, 
CNN RSS being down or feed missing/wrong URL. Try again with 
a different feed to see if that helps.
